Fluid
It is not necessary to check the
transmission fluid level.
A transmission fluid leak is the
only reason for fluid loss. If a leak
occurs, take the vehicle to the
dealer and have it repaired as soon
as possible.
Change the fluid at the intervals
listed inMaintenance Schedule on
page 11‑3, and be sure to use
the transmission fluid listed in
Recommended Fluids and
Lubricants on page 11‑12.
Notice: Use of the incorrect
automatic transmission fluid may
damage the vehicle, and the
damages may not be covered
by the vehicle warranty. Always use the automatic
transmission fluid listed in
Recommended Fluids and
Lubricants on page 11‑12.
The transmission fluid will not reach
the end of the dipstick unless the
transmission is at operating
temperature. If you need to check
the transmission fluid level, please
take the vehicle to your dealer.
Engine Air Cleaner/Filter

scheduled maintenance intervals
and replace it at the first oil change
after each 80 000 km (50,000 mi)
interval. See
Maintenance Schedule
on page 11‑3 for more information. If driving in dusty/dirty conditions,
inspect the filter at each engine oil
change.
See

on page 10‑6 for the location of the
engine air cleaner/filter.
How to Inspect the Engine

off, dirt can easily get into the
engine, which could damage it.
